Our redesigned Colorado River Basin map depicts the seven Western states that share the Colorado River with Mexico. The Colorado River supplies water to nearly 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming and the country of Mexico. This beautiful 24×36-inch map, which is suitable for framing, explains the river’s apportionment, history and the need to adapt its management for urban growth and expected climate change impacts.

We have two Colorado River-related Layperson’s Guides. The Layperson’s Guide to the Colorado River covers history of the river’s development, the division of its waters, the items that comprise the Law of the River and a chronology of significant Colorado River events. The Layperson’s Guide to the Colorado River Delta covers that important estuary, wildlife habitat and farming region even though Colorado River flows rarely reach the sea.
